Problems solved by technology

In this case, the use of positioning pins can also be considered, but there are problems in that it is not suitable for small products and the number of parts increases, which increases the cost
[0005] However, in this case, there is a problem that the length to the protrusion of the locking portion needs to be individually set according to the thickness of the flange portion or the dimension to the recess.
Moreover, when the side wall surface adjacent to the other sealing surface is a flat surface without a portion for locking the protrusion, it cannot be used at all.
[0006] Patent Document 3 discloses a structure in which protrusions are abolished, and flat-shaped locking portions are bent toward the inside at an acute angle and held by its elastic force. However, there is a problem of damaging the opposing wall surface when the gasket is assembled.

Abstract

The present invention addresses the problem of providing a gasket configured so that, during the mounting of the gasket to a counterpart member, the gasket can be self-retained without requiring a catch formed on the gasket body to be engaged with the counterpart member and will be unlikely to damage a counterpart wall surface. In order to solve this problem, the gasket is configured so that at least two catches (15) coming in contact with sidewall surfaces adjacent to a counterpart seal surface will be formed in a protruding manner on the gasket body (11) comprising a metallic base plate, thecatches (15) respectively having curved sections (152) formed at the front ends of the catches (15), which come in contact with the sidewall surfaces, at least one of the catches (15) being formed bent toward the inner side of the gasket body (11) so that the angle formed between the gasket body (11) and the at least one of the catches (15) will be an acute angle, the spring force of the at leastone of the catches (15), which is formed bent to the acute angle, pressing the bent section (152) against a sidewall surface to cause the gasket body (11) to be self-retained on the counterpart sealsurface.

Description

technical field [0001] The present invention relates to a gasket. Specifically, at least two locking claws are protrudingly formed on a gasket body made of a metal substrate, and the locking claws are in contact with a side wall surface adjacent to a counterpart sealing surface. gasket. Background technique [0002] Seal between two parts by sandwiching a gasket between them to prevent sealing fluid from leaking to the outside. The assembly of the gasket is carried out by placing the gasket on the opposite sealing surface of one part, covering the other part, and then fastening the two parts with bolts. [0003] When the gasket is placed on the counterpart sealing surface, the position of the gasket may shift or fall off from the counterpart sealing surface. It is especially obvious when the opposite sealing surface is horizontal or downward. In this case, the use of positioning pins can also be considered, but there are problems in that it is not suitable for small produ...
